EBS ISO 7638 7-Pin Trailer ABS OBD Diagnostic Adapter

Perform independent electronic brake diagnostics on heavy-duty trailers without connecting to a tractor engine. This ISO 7638 7-pin adapter meets CE and RoHS certification standards while bridging your scan tool to a trailer’s Electronic Braking System (EBS). Powered by a 5V-24V supply via the OBD-II interface, it supports K-line and CAN bus communications to interact directly with the trailer control unit.

Compatible Scan Tools: This hardware functions as a dedicated converter for major commercial vehicle diagnostic platforms. It is verified to work with the following scanner brands:

• Bosch Truck Scanners
• Autel Truck Diagnostic Devices
• Launch Commercial Vehicle Scanners
• Autocom Diagnostic Interfaces

Supported Trailer Electronics: The adapter targets specific European braking architectures and legacy systems used in cargo vehicles. Compatible braking systems include:

• Knorr-Bremse TEBS and TEBS G2.0/2.1
• TEBS 4 (Haldex G1) manufactured circa 2001
• Haldex EB+ Generation 2 (circa 2006)
• Haldex EB+ GEN3 (2011 and later)

Incompatibility Notice: Do not use with Delphi systems. This adapter also does not support Wabco TEBS C (approx. 2004), TEBS D (approx. 2008-2009), or TEBS E systems (around 2013). Batteries are not included.

Diagnostic Functions: Beyond reading fault codes, this interface allows technicians to execute active service procedures. Operations enabled on supported systems include performing valve checks, programming new valves, saving programs to disk, deleting daily operations data, and viewing current real-time parameters.
